Quality Control

Our 3-[[4-(Benzoyloxy)-2-Hydroxyphenyl]Azo]-2,6-Pyridinediol is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC and spectroscopic methods, to meet precise customer specifications. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
